Protosts are a gelatinous alien species from the moon Myceto.[pop-up 1][1]
Appearance
Protosts are pink blob-like aliens with a pair of antennae on their head and three yellow pupil-less eyes with black stripes running down the back and sides.
Only male Protosts have been seen, so it is unknown what female Protosts look like.
Diet
Protosts have their own equivalent of Human coffee: a slightly opaque white liquid with small alien fish swimming around.[pop-up 2][1]
Powers and Abilities
Protosts bodies are made of liquid slime, which they can control and shapeshift at will. They can morph and take on the shape of a blob for faster movement; stretch or elongate parts of their body; and slip through small spaces. They can even spawn tentacles to grab or interact with things.[1]
Protosts can envelop people or objects in their slime to shield them from outside attacks, or to shield the outside from dangerous objects, as Gluto did to protect Gwen.[1]
Protosts have exceptional healing capabilities, and are able to regenerate completely from any subdivision of themselves, no matter how small, as long as that piece of them doesn't evaporate first.[pop-up 3] Its only flaw is that they seem to take a while to completely regenerate their entire bodies.[1]
Protosts are very strong, as Gluto was able to wrestle with Vilgax, pick up and toss his Crewmen with one tentacle, and rip them in half.[1]
Protosts' gel-like bodies makes them invulnerable to most physical attacks.[pop-up 4][1]
Protosts are very quick and agile when they move as one blob, easily able to overwhelm opponents and dodge their attacks.[1]
Weaknesses
Energy Attack Vulnerability
Protosts are weak to energy attacks.[pop-up 5][1]
Known Inventions
The Protosts have hunting equipment, which the Null Void Containment Eggs that Ben 10,000 would use in the future are based on.[pop-up 6][2]
Notable Protosts
Etymology
The name Protost is a play on protists, which are any eukaryotic organism (that is, an organism whose cells contain a cell nucleus) that is not an animal, plant, or fungus.
Trivia
- Despite having a body of seemingly uniform composition, Protosts can still both blush and sweat, as demonstrated by Gluto.[1]
- A Protosts' multiple limbs allow them to control and pilot vehicles that few other species can.[pop-up 7][1]
